7mm 150gr. Winchester Power Points

I was given some Winchester 150gr. Power Point factory ammo when I bought my 7mm STW.It shot them really well so I decided to buy some bullets for reloading.WOW! shot a one ragged hole three shot group with them.Looks like I may have to give them a try on deer and hogs this coming season.Anybody use them and how do they perform at high velocities?
